Kentico CMS comes with automatic support of the Google Sitemap Protocol. This is a protocol designed to help search engines with indexing of your site and can improve your site's position in search engines. Simply put, a Sitemap is an XML file where URLs of your site are stored. Detailed information about the Sitemap Protocol can be found at https://www.google.com/webmasters/tools/docs/en/protocol.html.
Kentico CMS creates your site's Sitemap automatically. Physically, it is located at <domain>/CMSPages/googlesitemap.aspx. It can also be accessed through the URL specified in Site Manager -> Settings -> URLs -> Google Sitemap URL. This value is set to googlesitemap.xml by default, which means that the site's Sitemap can also be accessed throught <domain>/googlesitemap.xml. This is the URL that you enter into google when registering a new sitemap.
Please note that if you want the Sitemap to be accessible via the URL with .xml extension, you need to configure your IIS to handle the 404 error by Kentico's handler404, as described in this chapter. In this case, it is also necessary not to set the .xml extension to be processed by .NET.
